Non-Arthroscopic Lysis and Lavage - CDT Code Guide
Overview
CDT Code D7871 refers to a non-arthroscopic lysis and lavage procedure, primarily used in the management of temporomandibular joint (TMJ) dysfunctions. This procedure involves the insertion of inflow and outflow catheters into the joint space to facilitate lavage. The joint is then manipulated to release minor adhesions and alleviate the synovial vacuum phenomenon. Additionally, this process helps in removing inflammatory products from the joint space, providing relief from pain and improving joint function. Typically, this procedure is indicated for patients experiencing TMJ pain due to minor adhesions or inflammation that do not respond to conservative treatments.
When to Use This Code
- Patients with TMJ pain unresponsive to conservative treatments
- Cases of synovial vacuum phenomenon in the TMJ
- Presence of minor adhesions in the TMJ

Documentation Requirements

- Radiographic evidence supporting TMJ dysfunction
- Clinical notes on previous conservative treatments attempted
- Informed consent documentation
- Operative report detailing the procedure
